- LCLisa Cooper1 day ago5.0Austin and Nick did a great job installing our tankless water heater. They were really friendly and professional! Like to give a shout out to Heather as well! Great company and we highly recommend!
- FHFred Hatchett1 day ago3.0Update….. I asked for two things to be replaced. A ball valve and inlet valve to bathroom sink. 1000 bucks is absurd for what I wanted. Tech wanted to redo entire setup. That’s not what I asked for. I came home from work to fix the issue myself. Took about 10 min and 25 in parts. I don’t expect cheap labor. But come on now. I did not see my 68 service charge. I’ll send check in mail if I don’t see the charges on my card soon. I will never expect anything for free. Thanks for coming out!!
- JSJaired Segrest4 days ago5.0We were lucky enough to have Nick Hill as our technician today. He was very nice and friendly. He was inquisitive about our problem and was very straightforward with us on how the process would go.
